Sources claim that Karunanidhi has been admitted to Kauvery hospital and will remain in the hospital for a few days until the treatment and check-ups are complete.

"He is stable and being treated by a team of doctors. He will be in the hospital for few days," Aravindan Selvaraj, Executive Director of the hospital said.

Karunanidhi has been avoiding public appearances for the past one month as he was undergoing treatment for an allergy and had skipped campaigning for the bypolls to three Tamil Nadu Assembly seats last month.
